Brazilian Barin/e 179 



Elytra with flat intervals, which are coarsely, unevenly and more or less densely 

 punctate 3 



3 — Form elongate-suboval, narrower and not at all rhombic. Pale whitish 

 squamules of the pronotum forming a lateral and discal loose vitta at each 

 side, on the elytra rather scattered but condensed apically and in a small 

 spot at base of the third interval and on the fourth near basal third, also in 

 a longer, more conspicuous spot at three-fifths; on the under surface dense 

 on the abdomen, but irregularly smaller and sparser throughout the sterna; 

 beak (cf) barely longer than the head and prothorax, strongly sculptured, 

 only feebly tapering beyond the thicker basal part, with the antennae at 

 three-fifths, or ( 9 ) a little longer, relatively more inflated basally and much 

 more slender, smoother and tapering distally, with the antennae just beyond 

 the middle, the latter obscure rufous; prothorax about as long as wide (o 71 ), 

 a little wider ( 9 ), the sides feebly arcuate, more rounding anteriorly, the 

 tubulation gradual and only feebly defined, half as wide as the base; punc- 

 tures coarse, deep, very dense and longitudinally confluent, the obtuse smooth 

 carina conspicuous, fine at apex; basal lobe nearly as in the preceding, the 

 scutellum narrower; elytra oval, three-sevenths longer than wide, nearly a 

 third widen than the prothorax and more than twice as long; grooves coarse, 

 deep; intervals with coarse and confused punctures, slightly separated; 

 male with the abdomen feebly flattened and slightly less coarsely and more 

 loosely squamulose at base. Length 54-5.6 mm.; width 2.35-2.75 mm. 

 Brazil (Santarem). Two specimens carinulatus n. sp. 



Form stouter and evidently subrhomboidal 4 



4 — Elytra with the condensations of pale yellowish scales arranged as in carinu- 

 latus. Body much larger in size, stouter and rhombic-oval, piceous-black, 

 not shining; slender squamules pale ochreous in four loose vittae on the 

 pronotum, on the elytra arranged much as in carinulatus, those of the under 

 surface paler, also similarly arranged; beak similarly rather closely squamu- 

 lose, inflated and coarsely sculptured basally, only feebly tapering distally 

 (cf) and with the antennae at three-fifths, or much more slender, smoother 

 and more tapering distally, with the antennae slightly beyond the middle 

 ( 9), nearly similar in relative lengths and moderate curvature to the pre- 

 ceding species; antennae piceo-rufous; prothorax a fourth (o 71 ) or two-fifths 

 ( 9 ) wider than long, the sides subparallel, rounding beyond the middle to 

 the feebly defined tubulation, which is half as wide as the base (o 71 ), much 

 less ( 9 ); punctures coarse, very deep and dense, the smooth carina narrow, 

 strong and entire; basal lobe broad, short and very gradual, with the apex 

 narrowly and feebly sinuate; scutellum tumid, obtrapezoidal, somewhat 

 squamulose; elytra three-sevenths longer than wide, rather obtusely para- 

 bolic, a third wider than the prothorax and slightly more than twice as long, 

 the humeri not prominent but rapidly oblique to the base, rounded externally; 

 grooves coarse and very deep; intervals nearly flat, coarsely, deeply and 

 densely, confusedly punctate; male with the abdomen broadly and feebly 

 impressed and less squamose medio-basally; sutures strongly reflexed at the 

 sides as usual. Length 6.4-7.8 mm.; width 3.1-4.0 mm. Brazil (Santarem). 

 Two specimens insignis n. sp. 



Elytra with the condensations of pale scales similar, except that the one on the 

 fourth interval, near basal third, is always wanting, and that the scales on 

 the inner intervals in apical third are much denser and more conspicuous; 

 body smaller in size and especially much more briefly rhomboid-suboval. . .5 



5 — Body stout, rhomboidal, black, with the scales of the upper surface large, 

 dense and dark brown in color, sprinkled with some large whitish ones on 

 the pronotum and, on the elytra, condensed at the base of the third interval 

 and throughout apical two-fifths of the elytra, except on the lateral intervals
